Application filed March 7, 1916. Serial No. 82,649.

To all whom t may concern.'

lle it known that we, ALBERT Coi-IN and Louis Dres, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Strainer-s, of which the following is a specification.

rlliis invention relates to a strainer adapted for use with receptacles, such, for instance, as coffee pots, and is concerned particularly with the strainer construction and the means for holding it in place.

Qur invention includes, among its objects, the construction of a strainer readily attachable or detachable as often as desired; a strainer equipped with means for holding it tightly in position so as to prevent leakage of particles tlierearound; a strainer in which the holding means serve also as a catch for the receptacle lid; and a strainer which is simple and durable in construction, and economical of manufacture as Well. rlhese and other objects of our invention ivill more fully hereinafter appear from the specification and claims, and from the drawing in which:

Figure 1 is an elevation of an ordinary coffee pot, a portion thereof being broken aii'ay toexhibit in section` the strainer of our invention applied in position;

Fig. :2 is al fragmentary vieiv of the coffee pot showing in plan the strainer applied in position; and

Fig. 3 is a fragmentary view showing in cross section a coffee pot equipped With the present strainer, the holder thereof being of sli 0litly modified construction.

rlhe device of our invention is illustrated in connection ivith an ordinary coffee pot equipped ivitli a handle 5, a lid 6, and a pouring spout 7. The nerforations 8 ordinai-ily provided in the Wall of the pot adjacent the spout being insufficient to strain the liquid, -ive have provided a strainer 9 arranged to lit Within the pot adjacent the perforations 8, this strainer boing the subject mattei' of thepreseiit invention.

The strainer may be formed of a suitable iif'ire mesh, or other fo-raminoiis material adapted to prevent passage therethrough of particles. ns slioivn in Figs. 1 and 2, a ivire holder 10 is secured to the strainer by any approved means suoli, for instance, as by soldering or brazing. rthis holder consists preferably of a pair of arms 11 (see Eig.

2), each secured to the strainer at points relatively near its upper and loiver edges. it is desirable that this Wire holder should be formed of spring material for the pur pose of insuring the retention of the loiver edge of the strainer against the Walls of the pot when the holder is clamped over the upper edge 12 of the pot :in a manner to be presently explained. At their upper ends the arms 11 project slightly beyond the upper edge of the strainer, being looped around as at 18 and bent downwardly again as at 14- to engage with the exterior surface of the pot. It will be observed that the portions 1t of the holder are so shaped as to lie at their lower extremities relatively close to the arms 11. As the holder is formed of spring material, these portions 1st are capable of being sprung away from the arms 11 in order to pass over the edge 12 of the pot into clamping position. The upper pot edge designated as 12 is ordinarily rounded and beaded as sho* in in Figs. 1 and 3.

The lower ends of the portions 14 of the spring holder are looped around as at 15 to provide upwardly extending portions 16,

which near their extremity are providedv with a crimp or inward bend 17, as best shown in Figs. 1 and 3. As appears from 'Fig' 2, the holder is looped across at 18 in a manner to permit the entire holder to be formed of a single piece of ivire. This crimped portion 18 serves as a catch for the receptacle lid 6 to hold it firmly in place. The entire holder is formed of spring material, the catch swinging from a point adjacent the loop 15 to normally retain the lid in place. Under sufficient pressure the catch may yield, of course, to permit the lid to siving into and out of engaging position.

In Fig. 3 ive have shown a very similar construction, the only diiferenee being in the shape of the holder arms 11 which are bowed as at 19. 'This construction is advantageous in that it insures a tight retention of the loiver edge of the strainer against the interior surface of the pot. Such retention is manifestly necessary, as otherwise particles of matter could pass around the strainer and out through the spout.

From the foregoing description, it is manifest that the present strainer consists of but tivo elements, viz: the strainer itself and the spring holder. The holder is so constructed and arranged With respect to kagainst displacement.

the strainer as to insure its tight retention against the inner Wall of the pot fronrend to end, thus eiectually straining all particlesV of matter moving toward the perfora` tions 8. The spring holder, moreover, is so arranged as to enable the strainer to be clampedV in position, to be held tightly The construction of the holder is such, furthermore, as to pro` vide a catch for the lid, thus holding it lirmly against movement. As the various portions of the spring holder are capable of yielding under pressure, it is obvious that the entire strainer may readily be removed from the pot, and that the lid may be opened against the tension of the catch. These objects, as We have shown, are attained by the very simple and edective construction of our invention.V

We claim:

l. A st rainer of the kind described, em` bodying, in combination, a sheet of strainer material adapted to it against the side of a receptacle, and a holder for the strainer Y formed of spring material and arranged to hold the strainer against the receptacle, the holder comprising companion arms secured to -V the ystrainer and looped around to overlie one edge of the receptacle and clamp thereupon, whereby the strainer is held firmly against the receptacle, the clamping portions ofthe holder being upturned to provide a spring catch for the lid of the receptacle, the acting end of the catch being rounded to facilitate move-k strainer and arranged to hold the same tightly against the receptacle, the holder being formed of spring material bent to clamp over an edge or the receptacle, whereby the strainer is iirmly held in place, the holder being provided with an upturned portion arranged to engage With the lid of the receptacle to constitute a spring catch therefor, substantially as described.

' 3. A device of the kind described embody ing in combination a strainer adapted to lit upon a receptacle, and a holder for the strainer arranged to hold the same in position upon the receptacle, the holder being provided with a member arranged to engage With the receptacle lid to constitute a catch therefor, substantially as described.
